Ever need an extra pair of hands? So did Federico Parietti and Harry Asada of MIT. They've created a pair of semi-autonomous robot arms that you can wear:
To demonstrate what the prototype can do, a camera observed a pair of workers helping each other drill into a loose metal plate. The camera measured the distances between the tools and work surface, while feedback from sensors on the workers' bodies tracked their movements. This taught the arms where to grab and how much force to apply, so it could then assist a lone worker to both hold the drill and secure the plate.
